  • This device contains a channel that can be inserted into the interior of the patient, with a path for inhalation and a separate path for exhalation, and one
  • Air flow control within the device for controlling the breathing air flowing through the inhalation path to expand the patient's lungs and to allow the air to be exhaled to flow through the separate exhalation path to clear the sputum from the Remove patients through this exhalation path through the force of the air exhaled from the lungs.
  • This device for controlling the air flow provided inside the patient cannot be monitored from the outside, so that its perfect functioning can only be suspected. The help required in the event of a malfunction often comes too late. Therefore, this device has not established itself in practical operation.
  • a tracheal catheter known from DE 35 24 126 AI is still used in practice, the front end of which can be inserted into the trachea, for example, through an tracheal incision, while a connector is arranged on its rear end, which protrudes from the trachea on which, for example, an air hose for connection to a respirator or an air filter can be plugged, via which the patient can take in filtered, ie germ-free, breathing air.
  • the invention has for its object to supplement the known tracheal catheter such that the sputum is automatically kept away from the air filter and easily removed, so that the agonizing and painful suffocation attacks of the patient are avoided and the risk of suffocation is eliminated, even if the patient is left unattended for an extended period of time, such as several hours.

All three openings 1, 2, 3 are provided with cylindrical connecting pieces 11, 12, 13.
  • the inner wall of the connector 11 of the first opening 1 is conically shaped so that this connector 11 can be plugged onto the end of the tracheal catheter protruding from the trachea.
  • the connector 12 of the second opening 2 which is preferably directed upward in the position of use, has a conically shaped outer wall, onto which an air filter for cleaning and disinfecting the air to be inhaled can be plugged.
  • the connector 13 of the third opening 3, which is preferably directed downward in the position of use, has a conically shaped outer wall, onto which a collecting bag for collecting the sputum or a hose for the outflow of the sputum can be attached to such a collecting bag.
  • the valve for opening and closing the third opening 3 consists of a piston 5 controlled by the breathing air, which has a conical base surface 7 and a cylindrical outer surface 8 and is mounted in the cylindrical housing 4 in a slightly sliding, coaxial manner. In the closed state, the third opening 3 is covered by the jacket surface 8.
  • a coaxial cylindrical tube 9 is integrally formed on the cylindrical outer surface 8 of the piston 5, which receives a large part of a spring 6 designed as a helical spring, the other part of which is supported on a closure plate 10, one of which is at the first opening 1 opposite side of the cylindrical housing 4 covers existing fourth opening.

  • the inventor of the present invention has been testing the long-term function of a patient paralyzed by a stroke who is close to him under the supervision of doctors and nursing staff. It was not necessary to clean the device for days, while without this device the clogged filter must be replaced every ten to 15 minutes on average in acute cases.

Abstract

L'invention concerne un dispositif permettant d'enlever des mucosités se trouvant dans un cathéter inséré dans la trachée d'un patient. L'objectif de l'invention est de compléter un tel cathéter trachéen de telle sorte que les mucosités soient automatiquement maintenues à distance du filtre à air et enlevées sans problème, cela dans le but d'empêcher des cas d'étouffement du patient pénibles et douloureux et d'éliminer le risque de mort par étouffement. Cet objectif est atteint grâce à l'utilisation d'un boîtier (4) comportant: une première ouverture (1) pouvant être reliée à l'extrémité du cathéter trachéen sortant de la trachée; une seconde ouverture (2) permettant l'échange air expiré-air frais filtré; et une troisième ouverture (3) servant à l'écoulement des mucosités.
